Initial synchronisation of wideband and UWB direct sequence systems: single- and multiple-antenna aided solutions [PDF]
, 2012 This survey guides the reader through the open literature on the principle of initial synchronisation in single-antenna-assisted single- and multi-carrier Code Division Multiple Access (CDMA) as well as Direct Sequence-Ultra WideBand (DS-UWB) systems ...
